8. FAQ

  • What are the time controls mean?
    Time controls are telling you how much time you have for each game.
    G12;d5: Game in 120 minutes (aka 2 hours) with 5 second delay with each move. This means you get 120 minutes, your opponent gets 120 minutes and at each move the clock counts down from 5 to 0 before the player's time starts. If player doesn't use up the whole 5 seconds, that time is lost.
  • How many games/rounds?
    The 7SS before the time control means how many rounds, i.e. how many games can a player play in the tournament. The tournaments are never elimination, so win or lose you can stay in the tournament.
